Eikonal amplitudes from curved backgrounds
Tim Adamo, Andrea Cristofoli, Piotr Tourkine
Eikonal exponentiation in QFT describes the emergence of classical physics at long distances in terms of a non-trivial resummation of infinitely many diagrams. Long ago, 't Hooft p…
The Uncertainty Principle and Classical Amplitudes
Andrea Cristofoli, Riccardo Gonzo, Nathan Moynihan +4
We study the variance in the measurement of observables during scattering events, as computed using amplitudes. The classical regime, characterised by negligible uncertainty, emerg…
Waveforms from Amplitudes
Andrea Cristofoli, Riccardo Gonzo, David A. Kosower +1
We show how to compute classical wave observables using quantum scattering amplitudes. We discuss observables both with incoming and with outgoing waves. The required classical lim…
